Yinto eqhelekileyo ukusebenzisa umoya opholileyo othe nkqo ukupholisa iinkukhu kwixesha elishushu lasehlotyeni. Kufuyo lwamaqanda oluxinana kakhulu, isantya somoya kwiihoko yenkukhukufuneka ifikelele ubuncinane kwi-3m/s, kwaye isantya somoya kwindlu yeenkukhu kwindawo ezinobushushu obuphezulu kunye nobushushu obuphezulu kufuneka bufikelele ngaphezu kwe-4m/s ukuze ufumane “impembelelo yokupholisa umoya” engcono.
“Impembelelo yokupholisa umoya” ikakhulu ibhekisa kwisantya somoya ukunciphisa ubushushu bomzimba weenkukhu.
Isantya somoya sinokuba nefuthe elingakanani kubushushu bomzimba weenkukhu?
Ngokophando olwenziwe yiYunivesithi yaseGeorgia, isantya somoya sinyuke ukusuka ku-0m/s ukuya kwi-2.54m/s.°C.”
Ukuze ufumane isantya esiphezulu somoya, ndiyinto eqhelekileyo kukwenzaindlu yenkukhuisilingi, nciphisa umphakamo wehoko yeenkuku, okanye ukusuka phezulu kwihoko yeenkuku ecaleni kophahla olunxantathu ngokuthe nkqo phantsi kumgama ngamnye othile ukufakela isithinteli-moya okanye ikhethini yokuthintela umoya ukunciphisa indawo enqamlezileyo yehoko yeenkuku ukuphucula isantya somoya ehokweni.
Kutheni ukwenza oku, ikakhulu ngenxa yokuba isantya somoya sisondelelene nommandla onqamlezileyo weihoko yenkukhu.
Ukubalwa kwesantya somoya kwihoko yenkukhu enexesha elide: isantya somoya = umthamo wokungenisa umoya / indawo enqamlezileyo yehoko
Kucacile kule fomyula ukuba ukunyusa isantya somoya we-coop, mhlawumbi ukwandisa umoya we-coop, okt ukwandisa inani labalandeli abaxhathisa uxinzelelo olubi, okanye ukunciphisa indawo ye-cross-sectional ye-coop.
Ukwandisa abalandeli kuthetha ukunyuka kweendleko, ukwandisa ukusetyenziswa kombane, ukunyuka kweendleko zokugcina, kwaye ekuhambeni kwexesha ukongeza iindleko ezibalulekileyo zokusebenza kwishishini.
Emva koko ukunyusa isantya somoya kufuneka kuthathelwe ingqalelo ekunciphiseni ummandla onqamlezileyo weihoko yenkukhu. Ngezantsi siqonda utshintsho lwenkukhu yenkukhu ngaphambi nangemva kokunyusa ikhethini yokuthintela umoya ngokubala okuthe ngqo.
Umzekelo: inkukhu yenkukhu i-12m ububanzi, i-100m ubude, iindonga ezisecaleni ze-coop zi-2.4m ukuphakama, umbindi we-coop (ephezulu) yi-4.8m, i-coop ifakwe kunye ne-10 50 intshi ye-intshi, amandla okungenisa umoya we-fan nganye -50 Pa yi-31000m.³/h.
Emva koko isantya somoya sehoko yenkukhu kufuneka sibe: isantya somoya = umthamo wokungenisa umoya / indawo enqamlezileyo = 31000 / 3600× 10 / [12× (4.8 + 2.4) / 2] = 86.1/43.2 = 1.99m / s
Ukuba sifaka isilingi okanye ikhethini yomoya kwihoko yenkukhu, ukuze ukuphakama komphezulu wehoko okanye umphetho ophantsi wedrape ukusuka emhlabeni ube yi-3.6m, kwaye ukuphakama kwamacala omabini ehoko kuhlala kungatshintshi, isantya somoya = 31000/3600×10/[12×(3.6+2.4)/2]=86.1/36=2.39m/s
Ngoko ke, kwimeko yenani elifanayo labalandeli, ngokunciphisa indawo enqamlezayo yendlu yeenkukhu kunokunyusa isantya somoya kwisiseko se-0.4m / s yoqobo, oko kukuthi, ukusebenza kakuhle kunyuke ngama-20%, utshintsho lwesantya somoya oluveliswa yimpembelelo yokupholisa umoya lukwahlukile, umahluko phakathi kwempembelelo yokupholisa umoya emibini ehambelana nobushushu obumalunga ne-2.℃, kwimeko yobushushu obuphezulu obuphezulu, umahluko wobushushu obuyi-2℃kwanele ukwenza ingozi enkulu kwiinkukhu.
